The closest you can find to Jitter in the free software world is GridFlow, which supports the same "matrix-oriented" way of thinking. However it doesn't communicate with the DSP nor with OpenGL. In addition, it doesn't work well with PD (it's centered on jMax-2.5).

BTW, for anyone interested, I'm looking for someone to fix the bugs in GridFlow-for-PD. The reward is a big praise but also a (large) piece of software that works.

Let's see how big GridFlow is, for those who don't realize... That's over 50 object classes, several of which are extremely configurable. All ordinary math operations (40 of them) are all available through _one_ object class ([@]), and those 40 are also usable in other objects. There is also support for 6 number types, and 10 format handlers.

I don't think Gem does exactly what I want...

AFAIK, the commonly available version of GEM does only OpenGL, while there is a test version that also does straight video processing.

I have been very happy experimenting with GEM, and I would recommend it to you. If you delve a little deeper you may find some of the capabilities you're interested in are available already.

For instance, as i recall, GEM's pix_sig2pix~ will allow you to convert audio data to pixels, and pix_pix2sig~ does the reverse. There is a great possibility for visualizations of audio with PD and GEM. You could generate visuals and control video with FFT analyzers for a VU meter / winamp vis style effect. Or trigger video with midi for more correlation... or write a patch that manipulates video like a sampler manipulates audio.. or cut up video-recorded conversations and faces into new languages based on voice input from the audience...

I had some brief experience with Framestein, and it was positive, but it seemed there was more documentation for GEM, and GEM made more sense to me at the time.

The feedback loop idea is interesting to me, let me know how you progress. I don't know much about video, but video feedback always seemed like an interesting effect to play with..

When you have a concept for your installation in mind, PD and GEM might be just the tools to realize it.

But one thing I've learned is to have the concept first, and then find the technology to do it. If I spend to much time looking at nice technologies, I never get any concepts realized! :)

Ok...this is my deal. I've been hanging out for max/msp and jitter to come out for windows 'cos I only have cruddy macs at home. I finally gave up on it and have been looking at PD and what it can do with graphics. I've been getting the list digest for the last couple of weeks and thought it was worth asking...

I don't think Gem does exactly what I want...Framestein seems like it might be closer...but I can't find a hell of a lot of documentation to be sure.

Anyone have any suggestions? I kinda want to be able to make installations with an audio interface...controlling a screen which would probably be playing back from a bank of video clips...hmm...not a very good definition there...I don't completely know what I want to do =).

Any pointers would be joy!

Cheers
